srncrrrcnrron forming part o'f Letters Patent No. 681,271, dated August27, 1901.

Appncttion flied July 11, 1to0.

Lof theUnited States, residing at Ouray, in the `county ofOuray andState of Colorado, have invented certain new and useful Improve-lscription of the invention, such as will enable `others skilledin theart to which it appertains s IS to make and use thesame, reference beinghad l, `mentsin Ore-Concentrators; and I do declare the following to bea full, clear, and exact detothe accompanying drawings, and to the letapart of this specification.

"ters of reference marked thereon, which form This invention Vrelates toimprovements in l `ore-,concentrators of that class wherein a rotarymember fashioned to constitute a receptacle for the material to betreated is ein-l isc ;ployed,y whereby centrifugal force may be utilizedto a large extent in effecting the sepag ration of themetals from theores.' Briefly g stated,the invention may be classed as a cen- `trifugalore-separator. Thepresent invention is designed more par- 1 ticularly asan improvement on the appa-f ratus shown and described in United StatesLetters `Patent No. 648,088, dated April 24:, i 1900, issued toVmyself.` While in generali i principles `the machine is related to thattype of and is an improvement on the said pat-4 ented machine, yet theconstruction in manyl `particularsdifters materially therefrom andembodies features whi'chconstitute material improvements, resulting inadding great stability, easeof operation, more eifective separation,andpermitting of the control of the material, Aso that the separationmay. be governed readily, according to the character and state of thematerial being treated The objects of the invention are to provide asuitable supporting-frame for the separator, a clear-water-feedingdevice which will .have an independent source, means for adjusting thedelivery and collecting tubes so i that their receiving-openings may bevaried tosuit the character-of the material being treated, amechanismfor effecting the adjustment which can be operated during the operationof the machine, improved collectingpans, and in general features andconstructions presently to be described.

In the accompanying drawings I have shown Serin No. 23,214. (No man.)

` an embodiment of the invention, but desire it understood that variouschanges and modications can be made without departing from the natureand principle of the invention.

Figure l is a longitudinal vertical section showing parts in elevation.Fig. 2 is a side elevation. Fig. 3 is a section on the line a: ee ofFig. 1. Fig. 4 is a section on the line y y of Fig. 1. Fig. 5 is asection on the linee ,eef 6o Fig. l. Fig. 6 isa detail planof the rotarysleeve, its link connections, and Atube-adjusting means. Figs. 7 and 7aare detail sections ,l of the respective tube-adjusting and clampingmechanisms, and Fig. 8 is a detail per- 65 spective view of one of thetubes.

A designates a base which is conveniently constructed of four radialarms having a central hub or step-box A. The base A carries at theend ofits arms flanges a, and each 7o arm is perforated to receive ananchor-bolt a'. Secured to the flanges a are uprights B,

" which are obliquely arranged at a point a distance above their lowerends and extend up- `ward and inward, terminating in vertical sectionsb, which are boltedto yokes B B2, as shown in Fig. tt. i O designatesthe separator, which is conveniently of conical formation, having the`bottom C formed with its outer portion in- 8o clinin-g downward andthence directly outi ward, as at c, forming thereby an annular.collecting-channel, the side walls of which are inclined, as showninFig. 1. On the outside of the separator near its upper end is formed85 an integral pulley or belting surface C2, forming in addition ashoulder at the top, from the inner portion of which extends thevertical cylindrical bearin g c2, embraced by the yokes B and B2.

is enlarged s and formed into a hopper O3, the upper edges c3 of whichproject inward a short distance and constitute lips to prevent thematerial Into this 95 `from splashing out over the edge. hopper thematerial to be treated will presently be described.

D designates the supporting shaft or spindle, passing through the bottomC and supis fed, as

porting the separator by any suitable means 10o conveniently, such as ajam-nut d, located below the bottom and threaded on the shaft The upperend of the separator 9o above the cylindrical portion c2 or spindle. Thelower end of the spindle carries a detachable bearing D', having slopingsides and a depending center. This bearing is clamped to the spindle byhaving an up- Wardly-extending marginal flange engaging a groove in theend of the spindle, the flange being engaged by the clamping-band d, thetightening of which firmly presses and holds the bearing to the spindle.Other securing means for the bearing may be employed. In the step box orhub A/ is placed a steel bearing-block E, having a ball-raceway formedin its upper face and between which and the bearing D are a series ofballs e, thereby forming a ball-bearing for the spindle for theseparator'. The upper end of the spindle has cast integral therewith aflange or platform D2, having inclined upper faces. Below the platformare a series of radial fins d2, while above the platform are a series ofobliquelyarranged wings cl3, extending to the sides of the casing, asshown in my former patent, hereinbefore referred to. The extreme upperend of the spindle is reduced in size, tapered, and formed hollow, as atd4, the same terminating at a point below the upper end of the interiorof the separator. From the -hollow or tubular portion of the spindleextend channels d5 outwardly to the sides of the casing, where theycommunicate with pipes or channels F, formed in the sides of theseparator and extending downward to a point near the bottom thereof. Tosecurely unite the spindle with the walls of the separator, screw-boltsc4 are employed, passing through the walls of the separator into theplatform formed on the spindle. These bolts act in conjunction with thenut d, and by the in- -clination of the separator and the outer edges ofthe platform the wings and tins serve as a wedge, firmly binding orimpinging against the walls of the separator. With this construction avery rigid connection is formed.

G designates a water-s-upply tube entering centrally through the upperend of the separator and having threaded engagement with the upper endof the spindle. centered and held in place by any suitable means,conveniently by set-bolts g, passing through the hopper portion of theseparator at different points and radially.

g designates the funnel or receiver for the supply-tube G, the samebeing provided with an annularly-extending ring or flange g2 to preventthe contents of the funnel or receiver from being thrown outcentrifugally during.

the operation.

By the construction thus far described it will be observed that themachine is provided with means whereby a fresh and independent supply ofwater can be supplied to the interior of the separator and delivered atthe proper points, also that the machine is rigidly supported by theindependent frame and that the .driving-pulley is made a part of theseparator. However, other means fordriving the separator may beemployed.

This tube is Located in the outer walls of the separator at or near thelower edge are the collecting and discharge tubes H, their ends beingprojected a distance above the bottom of the separator. These tubes havelongitudinal apertures h therein, and the tubes are seated in suitablecavities or seinicircular grooves formed in the sides of the separator.The upper ends of the tubes are opened and communicate with the lowerends of the water-supply tubes F, so that the discharge of water isdirectly into the tubes H. To secure the tubes Hin their properadj ustedpositions,a conicalshaped split nipple J is employed, the same fittingin a screw-threaded aperture formed in the base O. Through this nipplethe tubes H pass and are clamped in position by a nut H', fashioned toengage the outer threaded surface of the split nipple .I and force thelatter closely against the tube. The nut H' is formed with an annularflange h at its outer end for purposes presently to be described.

K designates the discharge-tubes for the lighter materials. These tubesare secured by suitable nuts and split nipples, as heretofore described,passing through the bottom C at points inward or between the center andthe walls of the separator. The tubes K extend a considerable distancedownward, as shown in Fig. 1.

In such machines it is usually found necessary to vary the size ofthereceiving-openings of the concentrator or discharge-tubes H, and itisdesirable to effect this adjustment orvariation without stopping themachine. To yprovide for such, I have inserted in the tubes H theinterior or supplemental tubes L,which extend conveniently the entirelength of the tubes H and project a considerable distance below themachine.- These tubes L have registering receivingopenings Z of a sizecorresponding with the openings h in the tubes H, so that as the tubes Lare set to have the openings register the machine .will be set at itsfull capacity, but by turning the tubes L the size of the openings willbe correspondingly diminished. To effect this turning duringtheoperation of the machine, I secure to the tubes a split nipple M, whichembraces the projecting end of the tube L and is clamped thereon by theset-nut fm, fitting over the nipple. The end of the nipple M has acircular flange m', from which extends a semicircular flange fm2, fromthe edge of which extends inwardly a fiange m3, thereby forming asemicircular channel or receivinggroove, which when properly arrangedengages the flange 7i of the nipple H', and thus serving as a means forretaining the tube L in position, but permitting its rotation, the semicircular formation of the retainin g-ilan ge being for the purpose ofreadily applying the retainer to the nipple H and permitting itsremoval. From the iiange m' of the nipple M extends an arm N, to theouter end of which is attached a link O, which extends inwardlytangentially or at an angle to and IOG IIO

-IZO

\ is connected loosely with a collar P, sleeved s on the lower end ofthe spindle D. `This collar has an inwardly-extending pin p,which takesinto an oblique channel formed in the spindle, while PIO ` oppositesides, as shown. The yoke S is pivoted to a stud T on the base A and hasan upwardly-extending arm S', 'forming a bells. crank/to which theactuating-bar U is pivoted, the latter extending outward to and passingthrough a suitable slot in one of the g standardsor frames B, the endbeing threaded and having receiving-nuts u on opposite sides of the barB,so that its position may be "adj usted. By this means; it will be seenthat by drawing the bar U outward it will raise the inner end of theyoke'S, thus elevating i the ring R, which in turn elevates the collariP, carrying the same upward on the spindle l" YD, and by virtue of theinclined slot P' and `the pin entering therein the collar P will beturned slightly, thus drawing in on the links IO, and thereby turningthe clamping-nipple M slightly, according to the degree of movement, androtating the inner tubes L, thus carrying their openings transverselyandde- `creasing the inlet-openings to the tubes. By this means thevariation of the discharge- `iopening may be easily adjusted during the,operation of the machine. The tubes K Vand L discharge intoreceiving-pans V and V', i each of which are inclined gradually and arearranged in a circle. At the lower end of these receiving-pans are anysuitable dis` charge outlets or tubes, (not shown through whichthematerial is drawn and conveyed to any suitable place." Any desirabletype of `valve or gate may be employed for this pur- 1 pose. Itfrequently occurs that the position of the receiving-pans relative tothe end of the` discharge-tubes needs to be adjusted. Toelfect this,l convenientlysupport the pans by having suitable lugs c formed thereon,Qwhichfrest on blocks 1:2, held in position by bolts and nuts passingthrough vertical slots i v3, formed in the supports B.

Ihave described one discharge-tube, but4 it is to be understood thatfourwill ordinarily be employed, arranged an equidistance apart; but anydesirable number may be employed.

` In operation the material is deposited in `the hopper C3 and descendsinto the separator, ,at which point it is caught bythe wings d3 iand bythe centrifugal force is carried out- `ward, the material discharged atthe outer edges of the table D2, which table is cut away, I :leaving thepassages `d6 between its edge and spindle, the collar being susceptibleof in` same and pivotally connected therewith on the sides of thecasing, asshown in Fig. 5. The material being forced to thesidesof thecasing escapes into the separator below the table, and by the rapidrotation of the separator the heavier particles hug the sides, and.owing to the inclination of the sides of the separator, the dischargesbeing at or near the angle of juncture of the bottom and sides, thenatural tendency of the particles is to sink downward; but owing to theincreasing size and consequent peripheral speed (or belt-motion) kof thecasing the particles will not move on a meridian line, but constantlylag back from such meridian line with each successive point of movementdownward, and thus pass spicasing, pai-taking somewhat of thisincreasing motion by reason ofthe friction` on the sides, the result ofsuch action being that the heavier spective specific gravities huggingthe sides of the casing and made to passtransversely across the openingsin the discharge-tubes H, through which such portion as may be desiredis made to pass. As theyenter the disbythe incoming water received fromthe supply-pipe G and through the pipes F, the water serving also tokeep the discharge-tubes clear. Such particles and material as are notpermitted to be discharged through the slot in the discharge-tube Hcontiuuein the downward direction and are carried into thedischarge-tubes K. The inclination of the bottom C serves to force allthe material below the slot in the tube4 H to be discharged, `permitting no inert or neutral matter to remain, and thus causes a regularcontiniioualiow and movement of the particlesand material (pulp) inaccordance with the capacity of the machine or amount fed into it. rioustubes "the material is deposited into the receiving-pans V V.

The adjustment of the tubes having been described, their operation it isdeemed `un,-

Vthat the openings c' and h in the tubes may be set to register in suchlength asidesired less than the full capacity by inserting thetube Lfarther into the tube H, thus reducing the length ofthe slot. The sizeof such opening may then be diminished, as before described. Having thusdescribed my invention, what I claim as new, and desire to securebyLetters Patent, is s 1.
